Set times of all Jesmonite composite materials can be extended by the addition of Retarder to increase working time. There is a Retarder for AC100, AC200 and AC300, and a separate Retarder for the cement based materials AC730, AC830 and AC930. Please note that the end user should perform tests in the workshop environment, as extremes of temperature and humidity can effect set times. Addition rates can be found in the individual composite user guides.
